The inner end of the compression lever 21 is connected by a pair of parallel links 22, which links are in turn pivotally connected as at 23 to the laterally extending end 24 of the supporting strap 25. This strap 25 passes down under the rails 3 and is provided with an upwardly turned end 26. A suitable bolt 27 constituting a centrally located transverse bracing member passes therethrough and also passes through the rails 3 and carries a sleeve 28 which spaces the upstanding portion 29 of the strap 25 from the rails 3. lt is to be understood that this tool may be used in any suitable or desired manner and placed in any suitable or desired position to suit the convenience of the operator. It has been found convenient to place the tool against the chest or" the operator in compressing a spring so that the lever 21 may be pulled toward the operator in the compression ot' the spring thereby permitting the device to be very quickly and conveniently operated. It ot' course should be understood that the device may be mounted in any suitable or desired manner upon a bench or other suitable and convenient work place.

It is further desired to point out that this compressor may be used for the purpose of compressing valve springs of any particular type and may be used in conjunction with any suitable valve spring clips.A However, for the purp-ose of using the device inv conjunction with the particular clip which is described in my previous Patent #1,614,218, issued January 11, 1927, wherein a holder is disclosed having spring engaging arms for progressively engaging the convolutions of the coil spring, a special abutment plate is produced. This abutment plate is specifically illustrated in Figure 7 and comprises a disc-like abutment end 30 terminating in a laterally projecting tongue or shank 31 which is bifurcated as at 32 at its outer end to permit the bolt 19 on the compression shoe 18 to readily slide therethrough as the shoe 18 is drawn down toward the abutment shoe 7. The ends of the bifurcated portion 32 are slightly curved as indicated at 33 to facilitate the placing of the tongue or shank 31 under t-he sleeve 4 carried by the bolt 27 as will be obvious in considering Figures 2 and 5 of the drawings.

From the foregoing description it will be seen that a very has been produced in the nature of a valve spring compressor which may be very conveniently and easily operated. Simply by adjusting the abutment shoe 7 in the desired position upon the rails 3 and placing the spring so that one end thereof will engage the abutment shoe 7 and the other end engage the compression shoe 18, the lever 21 may be drawn inwardly or toward the operator, thereby fully compressing the spring at which simple and eiiicient device time the usual clip may be attached thereto or should the clip known as the VVainwright clip fully set forth in the above identified Patent 1,614,218, be used, the clip of course may be attached at the iirst instance to the spring and by compressing the same the clip will automatically and progressively engage the convolutions of the spring thereby automatically attaching the clip to the spring. This invention, of course, has particular reference to the compressor itself and not to the particular type of clip used in view of the fact that this device has been particularly designed to accommodate itself to the use of any particular clip desired in conjunction with the spring to be compressed.

lt should be further borne in mind that by producing a tool as described and illustrated, from round edge cold rolled steel or similar standard or stock material the cost of producing a very eiiicient as well as a sturdy tool has been reduced to the minimum.

It should be understood that certain detail changes in the mechanical construction may be employed without departing from the spirit of the invention, so long as these changes fall within the scope of the appended claims.

lVhat is claimed is:

1.

et. A valve spring compressor comprising a trackway, a shoe mounted upon said trackway, compression means associated therewith, said shoe comprising an upper plate, means for locking the same upon said trackway, a spring engaging inger anchored to the under face of said plate and extending upwardly at right angles thereto and adapted to engage one end of a valve spring while the same is being compressed or removed from a supporting clip, and a valve spring engaging means carried by said compression means.

5. A valve spring compressor comprising a trackway, a compression shoe slidably mounted upon said trackway, an operating lever ivotally mounted upon said compression s oe, a link engaging one end of said lever, a supporting strap secured to said trackway and provided with a. laterally extending end constituting a pivot support for said link, said strap passing down under said trackway and means passing through said strap for anchoring the same to said trackway.

6. A valve spring compressor comprising a trackway, an abutment member carried by said trackway, a removable abutment plate having a disc shaped end fitting against said abutment, means engaging the track for holding said abutment plate in position thereon, and compression means associated therewith.

7. A valve spring compressor comprising a trackway consisting of a plurality of side rails, an abutment member mounted upon said trackway, an abutment plate comprising an upwardly extending disc-like member, and a forwardly extending rib iitted between said track rails for removably supporting said abutment plate in engagement with said track rails, and compression means associated therewith.

8. A valve spring compressor comprising a pair of track rails, means supporting the ends thereof, a centrally located transverse bracing member extending between said track rails, a strap extending under said track rails, said strap being bent upwardly and havin a laterally extending end, a link supported thereby, a compressi n member slidably mounted upon said track rails, an operating lever carried by said compression member and engaging said link, an abutment member, an abutment plate removably engaging said abutment member, and provided with an upwardly extending disc-like portion, and
